I have 3 single Friedman mods that I've been hoarding. I don't have much history on them. I bought the 3 in a bulk deal. One is a supposedly HBE but modded to Steve Stevens specs. I could probably whip up some clips if you're interested. I would love to unload the 3 pack but let me know. Here's some pics on Tumblr. I'm thinking $250 each or 3 pack for $550? These are rare birds.

The mods are labeled on the bottom. They look and sound legit.
B.O. mod built on what looks like a Plexi module
C45/BE built on a Plexi mod with a saturation switch
BE/SS spec built on a Judge module
